Buyer backed out after reservation: what can the seller do?

The buyer paid a reservation amount and the listing was withdrawn. Now they say the mortgage failed, demand the money back, miss the purchase signing or simply changed their mind. “The fee is forfeited” is not a complete answer. The seller must separate the buyer’s exit, the seller’s remedy, the holder’s authority over money and the agency’s commission before relisting or claiming loss.

Identify what the buyer actually did

• Asked informally to cancel: a negotiation message may not be a valid contractual withdrawal.
• Invoked a financing or due-diligence condition: test the evidence, amount, deadline, effort and notice requirements.
• Failed to sign the next contract: identify whether the buyer was bound to sign and whether a formal demand or cure period is required.
• Withdrew from a signed purchase agreement: read the stated contractual or statutory basis and its consequences.
• Failed to pay or fund escrow: separate late performance, material breach, termination and any security or penalty.
• Acted after a cadastral filing: do not assume a message automatically stops the registration proceeding.

Ask the buyer to identify the document, clause, event and effective date in writing. Do not improve an unclear notice for them, but do not ignore it either. The response should preserve the seller’s position without declaring an exit valid or invalid before the full file is reviewed.

Map the documents and parties before choosing a remedy

Put the listing, offer, reservation, brokerage agreement, future agreement, purchase agreement, escrow, mortgage cooperation and cadastral documents in order. Mark who signed each one. A buyer-agency reservation can regulate a fee without creating the same seller-buyer obligation as a seller-signed future or purchase contract.

Use the reservation-agreement checklistto identify the fee and promised next step. If the buyer claims the seller caused the failure, compare the seller’s document, title, inspection, valuation and mortgage-cooperation duties against the timeline.

A mortgage rejection is not an automatic answer

Check whether financing was an express condition, which loan amount and bank decision count, the application deadline, buyer cooperation, required number of applications, valuation threshold, seller cooperation and notice method. A genuine rejection may satisfy a negotiated exit; an undocumented statement or an application outside the agreed parameters may not.

Request the evidence allowed by the agreement without demanding unnecessary sensitive banking data. The dedicated mortgage-rejection guideshows why low valuation, credit refusal, missing buyer documents and a title problem should not be treated as the same event.

Do not apply a universal “14-day cancellation” rule

The Civil Code contains consumer withdrawal rules for qualifying distance and off-premises contracts, including service contracts, with rules about requested performance and completed services. A real-estate transaction can contain a brokerage service, reservation promises and a property contract in one file. The signing location or electronic signature alone does not safely decide the effect on every obligation.

Have counsel classify the parties, contract and performance under Sections 1829 and following before accepting or rejecting a consumer notice. Do not present a blanket “14 days” statement to the buyer or use it to release money from a different legal relationship.

A consumer cannot always be penalised for not buying

Section 14 of the Real Estate Mediation Act prevents a brokerage agreement from imposing on a consumer the duty to conclude the property or future property contract. The Supreme Court applied that rule to the three-party “reservation agreement” in case 33 Cdo 1507/2022 and rejected the intermediary’s contractual penalty for failure to buy.

That judgment does not automatically return every payment or erase every seller-buyer obligation. It does mean the seller should not assume that an agency’s fee label becomes the seller’s enforceable penalty. Parties, substance, promised breach and payee still control the analysis.

The buyer may also point to the broker’s failure to provide a sufficiently current public-register extract or the disclosures required by Sections 11 and 12. Test that claim against the brokerage agreement and its statutory withdrawal consequences. Do not silently convert a valid exit from the brokerage relationship into cancellation of a distinct seller–buyer contract.

If a purchase agreement is signed, test the withdrawal itself

Under Sections 2001 and following of the Civil Code, a party may withdraw where the contract or law permits it. Section 2002 addresses material breach. Read the purchase agreement’s conditions, payment and cure deadlines, representations, defects, title, financing, cooperation and notice clauses. “I no longer want it” is different from a valid exit based on an agreed condition or the seller’s material breach.

Do not keep performing blindly and do not accept cancellation casually. Use the purchase, escrow and cadastral sequenceto coordinate a performance demand, termination, money and title. Confirm separately what happens to possession, documents, insurance and bank liens.

A penalty, damages and the reservation fee are not one pot

A contractual penalty under Section 2048 secures a specified duty. Section 2050 regulates its relationship with damages for the same breach unless the contract changes the default result, and Section 2051 allows a court to reduce a disproportionate penalty. A reservation payment, penalty, damages, price advance and agency commission therefore cannot simply be stacked and renamed.

• Identify the exact secured duty and triggering breach.
• Check which party is creditor and which party actually holds the money.
• Read set-off, retention, refund and accounting provisions separately.
• Calculate penalty and actual loss without automatic double recovery.
• Consider proportionality, consumer protection and the seller’s own performance.

The agency’s commission is a separate seller risk

The sale can fail while the intermediary still asserts that commission became due. Read the seller’s brokerage agreement, the event that earns commission, Section 19 of the Real Estate Mediation Act, any earlier-maturity wording, consumer instructions, termination and the agency’s role in the failed deal. Do not assume the buyer’s fee pays the seller’s commission or loss.

Use the seller commission guideto request an itemised basis before accepting an invoice, set-off or deduction from money held for another purpose.

Prove loss and reduce what can still be avoided

Build a loss ledger rather than naming a round amount. It may include a later lower sale price, duplicated title or legal work, financing and mortgage-payoff costs, extra carrying costs and other transaction-specific expense—but each item needs breach, causation, evidence and the correct contractual route.

Section 2903 matters where damage could reasonably be averted. Preserve the first transaction, then decide when and how to relist, continue maintenance, renew expiring documents and respond to serious alternatives. Do not leave the property idle merely to enlarge a claim; equally, do not create a conflicting second sale before the first transaction is safely resolved.

Check the cadastre before relisting as “available”

Use the official Czech cadastral viewerto inspect the current title and proceeding. If a purchase or mortgage filing is pending, coordinate withdrawal, consent, original deeds and escrow before signing with a replacement buyer. The plomba and title-risk guidehelps identify what a new buyer and their bank will see.

Send a clarification and preservation notice

This notice preserves facts; it is not a universal demand, recognition of withdrawal or election of remedy. Counsel should tailor any cure notice, performance demand, termination, set-off, penalty or damages claim.

Assemble one seller decision file

• All signed contracts, annexes, versions, powers of attorney and delivery evidence.
• Reservation money: payer, recipient, holder, account, legal label and current balance.
• Buyer notice, claimed reason, financing or valuation evidence and missed deadlines.
• Seller performance: documents, access, repairs, title cure, valuation and mortgage cooperation.
• Agency activity, commission agreement, invoice, accounting and communications.
• Current title sheets, filing references, escrow and original deed location.
• Loss ledger, invoices, carrying costs, later offers, relisting decisions and eventual sale.

Choose one coordinated outcome

• Complete the sale: preserve a valid demand and cure route, escrow, financing cooperation and filing.
• Agree a revised transaction: document new dates, price, conditions and costs without accidental waiver.
• End and relist: obtain a clear termination, money accounting, release of documents and safe availability date.
• Claim penalty or loss: identify the duty, creditor, legal basis, calculation, mitigation and interaction with every payment.
